[PATCH v5 0/4] qcow2: advanced compression options |
Date: |
Sun, 20 Oct 2019 23:37:04 +0300 |
New enhancements for writing compressed data to QCOW2 image.
v5: The new iotests cases were amended and 'qiov_offset' parameter
value in the function bdrv_driver_pwritev_compressed() invoked
from the bdrv_co_do_copy_on_readv() fixed to 0.
Discussed on the email thread with ID:
<address@hidden>
v4:
The 'compression' support at the block generic layer has been
accumulated in the separate patch 1/4. A little code refactoring
was made.
v3:
Instead of introducing multiple key options for many drivers, the
'compression' option has been introduced at the block generic layer
as suggested by Roman Kagan. Discussed on the email thread with ID
<address@hidden>
Andrey Shinkevich (4):
block: support compressed write at generic layer
qcow2: Allow writing compressed data of multiple clusters
tests/qemu-iotests: add case to write compressed data of multiple
clusters
tests/qemu-iotests: add case for block-stream compress
